There wont be much of a weight difference in the slipperential and Tranny.

Some things that MIGHT possibly break are the pushrods/hingepins/turnbuckles. Id reccomend some JDcarbon ones as they have all of these at a very affordable price! Less than 100$ shipped for 4 turnbuckles, 4 pushrods, and 12 hingepins.

Also arms, the stock ones will last, but in a hard crash they will break, id get front RPM arms with traxxas extended arms in the rear (or Tekno arms).
